The Amazfit T-Rex 3 Pro 48mm is the larger of the two sizes in Amazfit’s rugged T-Rex 3 Pro line, announced by Zepp Health in September 2025. It pairs a 1.5-inch AMOLED display under scratch-resistant sapphire glass with a Grade 5 titanium alloy bezel and buttons, a dual-colour LED flashlight, dual-band GPS supporting six satellite systems, and offline maps with turn-by-turn directions. Amazfit rates the 48mm battery at up to 25 days, and the watch works with both Android and iOS through the Zepp App with no subscription. This listing is the 48mm Tactical Black version.

Titanium and sapphire build
Amazfit builds the bezel and buttons of the Amazfit T-Rex 3 Pro from Grade 5 titanium alloy, the strong, light alloy used where knocks are expected, and covers the display with scratch-resistant sapphire glass. Together they protect the two places a rugged watch takes the most damage: the raised bezel that hits rocks, door frames and gym equipment, and the screen that slowly hazes over with fine scratches. Zepp Health states the watch is designed to work in temperatures as low as -30°C, which matters more on a winter trip abroad than in the Emirates, but shows what the hardware is built to handle.
A bright 1.5-inch AMOLED screen
The 48mm Amazfit T-Rex 3 Pro has a 1.5-inch AMOLED display, while the 44mm version uses a 1.32-inch panel. Amazfit quotes peak brightness of up to 3,000 nits. Peak is the maximum the screen can reach in bright conditions, not the level it holds all day, but it is what decides whether you can read a pace, a map or a heart-rate zone at midday without shading the watch with your other hand. AMOLED also gives deep blacks and strong contrast for always-on watch faces. Amazfit does not list the display resolution in its product description.
Dual-band GPS, offline maps and ski maps
Positioning uses dual-band GPS with support for six satellite systems. Dual-band reception improves accuracy where single-band watches struggle, such as between tall buildings, in narrow valleys or under tree cover. According to Zepp Health, the Amazfit T-Rex 3 Pro adds offline maps with turn-by-turn directions, smart rerouting, route creation and points-of-interest search, so you can follow a route without your phone. Ski maps show resort data, slope colour codes and lift locations. Amazfit does not name the six satellite systems individually in its official announcement.
Flashlight, calls and 180+ sport modes
A dual-colour LED flashlight is built into the case, with a Boost Mode for extra brightness, a red light for night use, an SOS flash and safety alerts. Amazfit does not publish a lumen figure. A built-in speaker and microphone allow Bluetooth calling from the wrist when paired with your phone, and the Zepp Flow voice assistant is supported. Amazfit lists more than 180 sport modes, including hiking, rucking, trail running, strength training, recreational scuba diving and official HYROX race and training modes, with a BioCharge energy score that combines workouts, recovery and stress.
Battery life and the 44mm alternative
Amazfit rates the 48mm Amazfit T-Rex 3 Pro at up to 25 days of battery life, compared with up to 17 days for the 44mm model. That headline figure reflects typical smartwatch use; long GPS recordings, high screen brightness, frequent flashlight use and calls all shorten it, and Amazfit does not publish the battery capacity in mAh. The 48mm uses 22mm straps such as Amazfit’s nylon and HYROX silicone straps, while the 44mm uses 20mm straps. The Zepp App on Android or iOS handles setup, health data and maps, and Amazfit states there is no subscription fee.
Who This Is Not For
The Amazfit T-Rex 3 Pro 48mm is a large rugged watch, so it suits poorly a slim wrist or anyone who wants a discreet dress watch; the 44mm model is the smaller option. It is not for buyers who want a large third-party app store on the wrist. Amazfit does not publish the weight, flashlight output or battery capacity in its product description, and health readings are wellness data, not medical measurements.
